Recently, when trying to watch a video in Amazon Instant Video, I only got Error 1002. I tried Firefox, Chrome, Opera and Internet Explorer and none of them worked. I reinstalled Silverlight and this also did not help.
Then finally I found the reason: Amazon still seems to use SSL 3 for Instant Video streams! Because Google recently reported security problems with SSL 3.0 (known as the POODLE security vulnerability), I disabled SSL 3.0 in all browsers including Internet Explorer. No matter what browser you use, Silverlight will use Internet Explorer’s settings and will not use SSL 3.0 any more. Re-enabling SSL 3.0 again in the Internet Explorer settings fixed the problem with Amazon Instant Video. As I am not really using Internet Explorer anyway, I don’t care much about this, but Amazon should really work on this to make Instant Video available without the need to enable SSL 3.0.
